Title: Air flow control for air seeders
Inventor: LANG FRANCIS G
IPC: A01C7/08
Filed: 1999-05-20
Granted: 2008-09-02
Abstract: An air seeder is provided with a control system for controlling the velocity of air flowing though the product delivery tubes between the product storage tanks and the planting mechanism for delivering the product into the ground. A multiple tank air seeder would be provided with a bank of product delivery tubes for each product storage tank with an air damper mechanism incorporated into each respective bank of product delivery tubes. An electric actuator is mounted on the air cart to connect to each respective air damper mechanism and effect the movement thereof between a fully closed and a fully opened position and, thereby restrict the movement of air through the product delivery tubes. The control mechanism includes a control panel from which the electric actuators for the air damper mechanisms and an electric actuator for controlling the rotational speed of the fan creating the flow of air through the product delivery tubes can be controlled. The air velocity is controlled by setting a base fan speed through the control panel and then sequentially setting the rotational position of each respective air damper mechanism so that each bank of product delivery tubes can have a different resulting air velocity for proper delivery of the product, e.g. seed or fertilizer, through the respective product delivery tubes.

Abstract: In a turbo coder, rate conversion and/or rate matching is achieved by deleting parity bits P1 and P2 from the outputs of two constituent coders, one supplied with data bits to be coded and the other supplied with the same data bits after interleaving. Deleted bits are determined by a rate matching control unit directly for the P1 bits and via a similar position interleaving step for the P2 bits. A similar rate matching arrangement is provided for only two of the three outputs of a rate 1/3 convolutional coder, the third output corresponding to a strongest coding polynomial in terms of minimum free distance and none of its coded data bits being deleted.

Abstract: L'invention concerne un procédé d'authentification permettant d'authentifier des communications échangées entre une première et une deuxième parties par l'intermédiaire d'une tierce partie qui a la confiance de cette première et de cette deuxième parties. Ce procédé consiste tout d'abord, pour la tierce partie de confiance, à calculer la valeur d'une première sortie d'authentification au moyen d'un paramètre de la première partie, ainsi qu'une seconde sortie d'authentification à l'aide de cette première sortie d'authentification, avant de transmettre cette seconde sortie d'authentification à la deuxième partie. Pour la première partie, ce procédé consiste à calculer la première sortie d'authentification et à transmettre cette première sortie d'authentification à la deuxième partie, laquelle calcule la seconde sortie d'authentification sur la base de la première sortie d'authentification transmise par la première partie, puis compare cette seconde sortie d'authentification calculée à la seconde sortie d'authentification transmise par la tierce partie de confiance. Ainsi, si ces deuxièmes sorties d'authentification correspondent, la première partie peut être authentifiée.

Abstract: The invention provides a process for preparing a platinum-ruthenium catalyst and the catalyst prepared therewith. The catalyst can be supported on a support material in powder form or may also be unsupported. To prepare the supported catalyst, the support material is suspended in water and the suspension is heated to at most the boiling point. While keeping the temperature of the suspension the same, solutions of hexachloroplatinic acid and ruthenium chloride are then added to the suspension, then the pH of the suspension is increased to a value between 6.5 and 10 by adding an alkaline solution and the noble metals are thus precipitated onto the support material. Afterwards, one or more organic carboxylic acids and/or their salts are added to the suspension and the catalyst is chemically reduced, washed, dried and optionally subsequently calcined under an inert or reducing atmosphere at a temperature between 300 and 1000 °C. The catalyst is characterised by a high tolerance to carbon monoxide poisoning in the fuel cell.
